矿井空气中粉尘含量的高低,直接关系着矿工们的身体健康。近十几年来越来越多的学者确认,呼吸性粉尘的重量浓度在矽肺致病方面起着重要的作用。从而促进了粉尘卫生标准的修改更新以及粉尘检测仪器的研制。为了了解该领域的发展并引以为借鉴,对世界各国的粉尘标准以及检测仪器进行探讨很有必要。一、各国采用的矿井悬浮粉尘标准各国矿井粉尘标准备不相同,每种标准
Mine dust levels in the air, directly related to the health of miners. More and more scholars in recent decades have confirmed that the weight concentration of respiratory dust plays an important role in the pathogenesis of silicosis. Thus promoting the revision of dust hygiene standards and the development of dust detection equipment. In order to understand the development in this field and draw lessons from it, it is necessary to discuss dust standards and testing instruments all over the world. First, the national standards for dust mines used in various countries Preparation of mine dust standards are not the same, each standard
